To all' whom) it ntcty concern:

Be it knownthat I, PERRY E. BRADLEY. a 4citizen of the United States,and a resident of Jersey City, in the county of Hudson and State of NewJersey, have invented anew and Irnproved Apron-Gruide for Mangles, fwhich the following is a full, clear, and exact description. Thisinvention relates to the guiding of aprons used on laundry machinery,such as mangles.

The object of theinvention is to provide im- -proved means forpreventing' the. aprons from creeping laterally upon their rollers.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

.in which similar characters of reference indicate corresponding partsin all the views.

Figure 1 is substantially a side elevation,

ypartly in section on the line 1 1 in Fig. 2, of

a mangle to which my invention has been applied, certain parts beingbroken away, as will appear. Fig. 2 is a section taken substantiallyuponthe line 2 2 of Fig. 1, certain parts 'being represented as brokenaway. Fig. 3 is an enlarged plan taken substantially upon the line 3 3of Fig. 1, showing mechanism just below this point, the parts of thesaid mechanism being broken away, as will appear. Fig. 4 is afragmentary elevation taken on the line 4 4 of Fig. 1. Fig. 5 is aperspective representing'a collar which constitutes a feature of theinvention, and Fig. 6 is also a perspective representing another collarwhich constitutes a feature of the invention.

Before proceeding to a detailed description of the construction andarrangement of the parts it may facilitate thedisclosure of theinvention to state that the mangle illustrated and to which theinvention has been applied is provided with two aprons, which are bothillustrated in Fig. l as provided with independent guidingor controllingmeans. Hen ceit will be understood that the mechanisms about to bedescribed are substantial duplicates of each other. i

Referring more particularly to the parts, 1 represents the frame of afour-roll mangle, said frame supporting a chest 2, above which the fourrolls 3 are mounted. At one extremity the frame is provided with theusual extensions 5, which are provided with inclined guideways 6 forboxes7 and 8, arranged in pairs on opposite sides of the machine, as

shown.

and B3 pass. dotted lines and pass as follows: The inside l apron B3passes down from the roller B, asindicated, so that its upper coursepasses along 6d" These boxes support worm-rollers and B, respectively,over which aprons A if These aprons are indicated in returning to theroller B. Theouter apron A3 in its lower course passes under a roller'A, whlch corresponds to the roller B, re-

ferred to above. Passing rearwardly from this roller the under course ofthis apron extends rarwardly and passes under a guide- 7o roller A2, andpassing upwardly in an inclined direction from the roller A"Z this apronpasses around a roller A'. From this point the upper course of the lowerapron follows substantially the same directions as the lower course ofthe inner apron, passing under the rollers B2 and B4 aforesaid.

As' indicated above. the-arrangement for effecting the guiding of theaprons is' duplicated for each apron. The mechanism to be de- 8o scribednow in detail is that used in connection with the outside apron A3.

Referring especially to Fig. 2, a shaft "is provided. which is rotatablymounted in boxes 8 at its extremities, and upon this sl.-' the roller Aaforesaid lis rigidly secured. points near the boxes 8'theshaft9 isprovic with rigid collars 10, provided on their inl:` faces,respectively, with a notch or recess 1 presenting an abrupt shoulder 12.Betwee the extremities of the roller A and these collars 10 wheels orcollars 13 are loosely mounted, said wheels or collars being providedon` theirfaces adjacent to the roller with anges 14. The bodies of thecollars 13 are provided i with chains a, which are attached at 16 andpass, as indicated, toward the floor. On the faces of the collars 13which lie adjacent to e of each of these pins is attached rigidly to amain arm 26, and these main arms 26 are l l i. 1

connected by a link 27. Upon the extremities of the short arms 24bearings 28 are swiveled, as will be readily understood, and

. in these bearings 28 are received the reduced extremities of the shaft29 of the guideroller A2. v f' It has been customary inpractice withsuch la mounting for the guide-roller A2 as that def ss kbon its roller.

connection with the worm-roller A affords means for performing thisfunction automatscribed to employ an operator who shifts by hand theroller in either direction, so as to control the position of the apronon its main rollers. Thus if the operator observed that the apron wascreeping toward the 4right he Ewould operate the roller toward the left,and this movement of the roller would bring about fin 'a short time acorrect position of the apron The mechanism described in ically. To thisend a connection is made through the chains a aforesaid to the link 27.

The course of the chains on both sides of the machine is identical. Theone on the right is shown in Fig. 1. The chain passes down from thevicinity of the roller A to a rhint near the iioor, 'where it passesunder a nini-ng sprocket-wheel a', whence it passes A.rwardly just abovethe Hoor to a second fiding sprocket-wheel a2. Passing verti- :lly fromthis point this chain passes around 4third guiding sprocket-wheel a3,mounted .i a suitable bracket a4, attached at a conenient point to theframe 1. The chain at `his point leads inwardly horizontally, so as'toruakea connection at 30 (see Figs. 3 and 4) with the extremity of thelink 27.

In the operation of the device, referring especially to Fig. 2, if theapron A3 should tend to creep toward the left the loose collar 13 at theleft would be engaged by the edge of the apron and moved longitudinallyalong the shaft 9. If this movement of the apron continues suilciently,the outer face of the collar 13 would eventually be broughtagainst theinner face of the corresponding collar 10 and i' an engagement would bemade between the -shoulders 18 and 12, whereupon the rotation of tlfeshaft 9 and roller A would be imparted to the collar 13. If the collar13 rotated, it would actuate the corresponding chain and The purpose ofthe brackets 21 with their arms 22 will now appear. reference is had toFig. 2. It should be understood that as the suggested rotation of thecollar 13 occurs in order to replace the apron' in its normal position acontinued rotation of the collar would bring about an engagement betweenthe cam-cheek 2O and the extremity of the arm 22, as shown. jects tosuch adegree that it' affords means for throwing the collar inwardly insuch a way as to disconnect the shoulders-12 and 18, returning thecollar 13 to its normal position at the end of the roller A.

From the operation described it will now be understood that the collars13 in connection with the collars 10 constitute clutch connections whichare closed automatically by the creeping of the apron in eitherdirection. Furthermore, both.of these clutches are automatically thrownout when a sufficient movement of the guide-rollers A2 or B2 has beenproduced.

The application `of the invention in no waj'T interferes with the normaloperation of a mangle. The boxes 7 and 8 would, as usual, be mountedupon adjusting screws 31, which would enable the tautness of the apronsto be readily adjusted by cranks 32.

Having thus described my invention, I claim In this connection This arm22 pro- IOO as new and desire to secure by Letters Patentl 1.
